Processes for recycling or reusing material resources have naturally appeared along with the history of technology development when need, resource scarcity, opportunities, and enabling technologies have combined conveniently with insight, intuition, and fortune. The current pressure for saving resources by efficiently integrating production and consumption processes requires the development of systematic approaches exploring opportunities and determining the best alternatives. While recent research has addressed the problem of directly connecting sources and sinks, we turn our attention to doing so with improved efficiency and at a lower cost. This work addresses the event of a systematic framework for the synthesis and optimization of the industrial process networks required by an economic system aimed at adding value to waste and minimizing the continuous need for non-renewable resources from a circular economy perspective. The systematic framework presented relies upon a novel model formulated as a superstructure that includes the transformation technologies needed for the revaluation of waste, which, in turn, raises resource-sharing opportunities otherwise ignored. The model is flexible enough to address primary uncertainty sources and manage different objectives (e.g., economic and environmental. A case study on hydrocarbons recovery from waste plastic illustrates the capabilities of the model, which proves to be a useful tool for the identification of the most promising routes for waste transformation and the less efficient processes where substantial improvement is required to increase their competitive edge. The methodology is valuable for the multiple actors involving the waste revaluation sector, from private companies to policymakers.

当需求，资源稀缺，机会和使能技术方便地与洞察力，直觉和财富结合在一起时，回收或再利用物质资源的过程自然会随着技术发展的历史而出现。当前通过有效整合生产和消费过程来节省资源的压力要求开发系统的方法来探索机会并确定最佳的替代方法。尽管最近的研究已经解决了直接连接源和汇的问题，但我们将注意力转向了以更高的效率和更低的成本进行连接。这项工作解决了一个经济系统所需的综合和优化工业过程网络的系统框架的事件，该系统旨在从循环经济的角度提高废物的价值并最大程度地减少对不可再生资源的持续需求。提出的系统框架依赖于一种新模型，该模型被构造为上层建筑，其中包括废物重估所需的转化技术，这反过来又增加了资源共享的机会，而这种机会本来就被忽略了。该模型具有足够的灵活性，可以解决主要的不确定性来源并管理不同的目标（例如，经济和环境）。有关从废塑料中回收碳氢化合物的案例研究说明了该模型的功能，它被证明是确定最有前途的废物转化途径和效率较低的过程的有用工具，这些过程需要进行实质性的改进以提高其竞争优势。该方法对于涉及废物重估部门的多个参与者（从私营公司到决策者）非常有价值。
